(Main)High-voltage switchgear and controlgear - Part 212: Compact Equipment Assembly for Distribution Substation (CEADS) for AC voltages up to 52 kV (IEC 62271-212:2022)
High-voltage switchgear and controlgear - Part 212: Compact Equipment Assembly for Distribution Substation (CEADS) for AC voltages up to 52 kV (IEC 62271-212:2022)
This part of IEC 62271 specifies the service conditions, rated characteristics, general structural
requirements and test methods of the assemblies of the main electrical functional units of a
high-voltage transformer substation, duly interconnected, for AC voltages up to and including
52 kV on the high-voltage side and service frequency 50 Hz or 60 Hz. The CEADS is
cable-connected to the high-voltage network for indoor and outdoor applications of restricted
access.
A CEADS as defined in this document is designed and tested to be a single product with a
single serial number and one set of documentation.
The functions of a CEADS are:
– high-voltage/high-voltage or high-voltage/low-voltage transformation;
and some or all the following:
– switching and control for the operation of the high-voltage circuit(s);
– switching and control for the operation of the low-voltage circuit(s);
– protection of the power transformer functional unit.
The main functions are integrated in the following functional units:
– high-voltage functional unit;
– power transformer functional unit;
– low-voltage functional unit.
NOTE For the purpose of this document a self-protected transformer is not considered as a CEADS, but as a
functional unit, designed and type tested to its own product standard IEC 60076-13:2006.

Appareillage à haute tension - Partie 212: Ensemble compact d’équipement pour poste de distribution (ECEPD) pour les tensions alternatives inférieures ou égales à 52 kV (IEC 62271-212:2022)
IEC 62271-212:2022 est disponible sous forme de IEC 62271-212:2022 RLV qui contient la Norme internationale et sa version Redline, illustrant les modifications du contenu technique depuis l'édition précédente.
L'IEC 62271-212:2022 spécifie les conditions de service, les caractéristiques assignées, les exigences structurelles générales et les méthodes d'essai des ensembles des principales unités fonctionnelles électriques d'un poste de transformation haute tension, dûment interconnecté, pour les tensions alternatives inférieures ou égales à 52 kV du côté haute tension, et avec une fréquence de service de 50 Hz ou 60 Hz. L’ECEPD est raccordé par câble au réseau à haute tension pour des applications à l’intérieur et à l’extérieur à accès restreint. Cette deuxième édition annule et remplace la première édition parue en 2016. Cette édition constitue une révision technique. Cette édition inclut les modifications techniques majeures suivantes par rapport à l'édition précédente:
- numérotation des articles alignée sur l’IEC 62271-1:2017;
- reformulation du titre et du domaine d'application du document;
- mise en œuvre des modifications relatives à la définition et aux essais d'arc interne en suivant l'évolution du concept de poste préfabriqué conformément à l’IEC 62271-202;
- examen général des principaux modes opératoires d'essai tels que l'échauffement ou l’essai diélectrique sur les interconnexions, compte tenu des équipements de commande, de la communication, des dispositifs de réseau intelligent et de l'intégration des composants;
- examen général des exigences d’installation, de fonctionnement, de sécurité et de maintenance.
Visokonapetostne stikalne in krmilne naprave - 212. del: Kompaktni sestavi opreme za distribucijske postaje (CEADS) za napetosti AC do 52 kV (IEC 62271-212:2022)
Ta del standarda IEC 62271 določa pogoje delovanja, naznačene karakteristike, splošne strukturne zahteve in preskusne metode ustrezno medsebojno povezanih sestavov glavnih električnih funkcijskih enot visokonapetostne transformatorske postaje za izmenične napetosti do vključno 52 kV na strani z visoko napetostjo in za delovno frekvenco 50 Hz ali 60 Hz. Kompakten sestav opreme za distribucijske podpostaje je s kablom priključen na visokonapetostno omrežje za notranjo ali zunanjo uporabo z omejenim dostopom. Kompakten sestav opreme za distribucijske podpostaje, kot je opredeljeno v tem dokumentu, je zasnovan in preizkušen kot en izdelek z enotno serijsko številko ter enim naborom dokumentacije. Funkcije kompaktnih sestavov opreme za distribucijske podpostaje so: – pretvorba z visoke na visoko napetost ali z visoke na nizko napetost in nekatere ali vse spodnje funkcije: – preklop in krmiljene za delovanje visokonapetostnih tokokrogov; – preklop in krmiljenje za delovanje nizkonapetostnih tokokrogov; – zaščita funkcijske enote močnostnega transformatorja. Glavne funkcije opravljajo naslednje funkcijske enote: – visokonapetostna funkcijska enota; – funkcijska enota močnostnega transformatorja; – nizkonapetostna funkcijska enota. OPOMBA: Za namene tega dokumenta se samozaščiten transformator ne obravnava kot kompakten sestav opreme za distribucijske podpostaje, ampak kot funkcijska enota, zasnovana in tipsko preskušena v skladu z lastnim standardom IEC 60076-13:2006 za izdelke.
